Using Monte Carlo experiments, we show how information criteria determine, in the presence of GARCH errors, an optimal lag length in univariate time series and causality tests. We illustrate the simulations by testing the presence of serial correlation in exchange rates as well as...

The conventional specification of the Engel function is modified to take full advantage of the characteristics of panel data, which are usually used to fit Engel curves. Empirical results based on Chinese data demonstrate the superiority of the proposed model.

An empirical bilateral oligopoly model is constructed to estimate the degree of dominance by the upstream and downstream industry. The model is applied to the beef slaughter and retail industries. The hypothesis of equal dominance is not rejected.

A time-series model of private consumption in South Africa is presented. Consumer expenditure is found to be sensitive not only to income, but also to the source of income, interest rates and measures of political and economic uncertainty.

A paper by Xepanadeas and Habib, that estimates dynamic demand models, is shown to contain some serious errors. Careful consideration of the adding-up condition is shown to be necessary when using demand systems with autoregressive disturbances. Misspecification testing should be used in all...

This research empirically analysed the relations between the difference in consumer's preference and the consumption growth rate in Japan. As a result, the close relationship between the two is revealed. This study has clarified the fact that as the income bracket becomes higher, the value of...

The relationship between suicide and business cycles is analysed using long Finnish time series for the period 1878-1994. The results clearly show that suicide increases along with age and is related to both GDP growth (inversely), bankruptcies and unemployment.

Based on UK data, this study uses parametric and non-parametric hazard models to assess the significance of pre-marital cohabitation in affecting patterns of first marriage durations.

Using fixed betting odds for football match outcomes this paper improves on previous versions of outcome uncertainty models of attendance demand by utilizing data on 'repeat' fixtures between two teams. This provides some control over the variation in match characteristics which influence...
